Lower MPG due to replacing tires?

Asked by Feb 18, 2009 at 02:45 PM about the 2007 Toyota Prius

Question type: General

My wife and I have owned our Toyota Prius for over a year now.  We have been averaging about 45-48MPG on a full tank of gas, with our local city driving.  However, recently, we've only been getting about 38-42MPG.  The only difference I can think of is, that we changed all four tires.  We bought some new tires at Costco.  The tires are all at the correct pressure.  Can different tires really make a 5MPG difference?  Thanks.

I don't think by changing the tires will make the 5MPG difference, although I might be asking if you have more items in your Prius, also I just had mine Prius service recently, and I notice the improvement of the fuel efficiency, plus, take your Prius for a long distance, high speed drive is good for it as well.

Yes, the tires make a THAT big of a difference. I did the same thing with my Prius. I did not want to replace the low-rolling resistance tires with the same so I opted for regular sedan tires. My MPGs dropped instantly. On the upside, the car handles much better as is no longer skittish on the freeway.
